JBL 305P MKII Reviews

Great Home Monitor Package!

By Gregg
Rated 5 out of 5
Date: 2023-01-14

I haven't used the speakers a lot yet, but everything so far is great! I very much appreciate having the cables, isolation pads and the Senal controller as part of the package. The cabinets are larger than I expected so I will eventually buy some floor stands and put them behind my work table to give me a bit more setback. Very happy with the purchase but I would also consider the smaller speakers.

Poor build quality and product quality. I am unimpressed with the quality of the product. My speakers sound different from each other. Monitor your product quality and don't do this.

I have a pair of 308 MkII (to jam on a PC) and 305 MkII (for a keyboard). I am blown away from the sound of both. I am an audiophile with expensive speakers in every room I can fit them including some that cost over 10K each and these little JBL studio monitors give just as much detail as the big boys.

All You Need

This is a great kit for hooking up your laptop to pristine studio monitors. It's all there and at a fair price. But most importantly, these JBL's sound terrific. They produce accurately and without strain. You can certainly spend more on 8" monitors and to some ears and on paper others may seem better, but to me, these JBL's look good enough on paper and sound fabulous in my studio. I would heartily recommend them.

Muffled Sound

Speakers sound went muffled after using it for 2 months. Terrible quality speaker wont be buying jbl products again as this is not the first product to blow on me in such a short period of time.

Is there an EU power cord version available? One for use in Germany?
Asked by: Ryan
It supports both US and European voltages so all you would need is a standard US to German plug adapter not a voltage convertor. Also, the end which goes into the speaker is the standard computer power cable format so a cable should be easy to find.

None of my audio output devices have balanced connections - yet the back of the 305P's only have balanced inputs. If I use, let's say an audio cable that has a TRS connector on end (going to the speakers), and an RCA cable on the other end (going to my audio sources), will this work with the 305's?
Asked by: Bernd
It will work. For instance, I use them with my phone headset jack as the source. It may pick up more noise, but that may be an issue only with very long cables and in a professional situation. I never noticed any noise with my setup.

Is there an EU option for the power cord? For example, a power cord that will be usable in Germany?
Asked by: Ryan
These speakers come with a standard three-prong connector and a cable like this: https://www.monoprice.com/product?p_id=5280 which should be easy to find in any country (with the appropriate wall plug).

Do I need anything else to connect to my Mac Studio? Cables etc
Asked by: Dan
Aside from the items included in this JBL 305P MkII Studio Monitor Kit, the only other item you will need is a short standard stereo aux cable such as the Pearstone Stereo Mini Male to Stereo Mini Male Cable - Black, 3' (B&amp;H # PEMMSA103B) which will be used to connect the computer's 3.5mm audio output (headphone jack) to the 3.5mm TRS input on the Senal PMC-II Passive Monitor Controller. If you are using a USB audio interface and want to connect the PMC-II and JBL speakers to the interface, you can use the audio output(s) from the interface and connect them to the right/left XLR-1/4&quot; combo jack inputs OR to the 3.5mm input on the PMC-II Monitor Controller using the appropriate cables (not included).

Can the amplifier be bypassed to use as passive speakers?
Asked by: Anonymous
This is an active speaker, with the amplifiers built in, so it would not be used as a passive speaker. JBL LSR708i 8&quot; Master Reference Monitor (Single), BH #JBLSR708I would be a very god quality passive reference monitor to consider.

Can you add a subwoofer?

Can you add a subwoofer?
Asked by: Steven
Yes, a subwoofer such as the JBL LSR310S 200W Powered 10&quot; Subwoofer(BH #JBLSR310S) is a great pairing for the JBL 308P MkII Powered 8&quot; Two-Way Studio Monitors. You would feed the subwoofer from your main output signal, then feed the monitors from the subwoofer outputs. Link to LSR310S here: https://bhpho.to/3DCLlTY
